Which orientation is the best?

I do a lot of abstract work and sometimes I lose perspective of up and down or right and left. Then I have to choose the orientation that works best for the piece. This is sometimes hard to do because I have vested myself into the work and certain parts of the work. The best thing to do is to set it aside and rotate it every day until I settle on one. I had one piece that I wired to hang both horizontally and vertically becuase I wanted the owner to have the versatility of changing the orientation.

This piece is one that I have been thinking about in the same way. I designed it one way but am not sure that a differnt rotation would benefit the piece.  Do you as the viewer have a preference?  This is an encaustic painting without any bells and whistles.  Just simple curves and soft colors except for the red winding through the piece.  I have been putting a lot of red ribbon images in my work.
